The invention discloses one kind based on the encrypted industry internet communication encryption method of dynamic random, it is related to industry internet communication field.This method generates key using dynamic random mode, in communication both ends clocked flip dynamic key production process；Both ends communicate in locally generated random number, and carries out random number exchange, makes the random number that communication both ends are owned by locally generated random number and other side generates；Both ends communicate according to two random numbers, by key schedule, generates identical key；Both ends communicate in communication process, AES encryption and decryption is carried out using identical key to data message.The data stochastic and dynamic variation of present invention generation key, key only local store, not in transmission over networks, effectively prevent the risk of transmission key in network, enhance communication security；Secondly, key effectively prevents the key leakage hidden danger that human factor is brought without human configuration management.
Description
Technical field
The present invention relates to the industry internet communications field, be related to it is a kind of randomly generate, the communication of dynamic interaction, cipher key calculation
Encryption method specifically, refers to a kind of based on the encrypted industry internet communication encryption method of dynamic random.
Background technology
Under industry 4.0, the overall background of made in China 2025, the Chinese industrial level of informatization steps up, industrial information
Safety is more important to the importance of development of manufacturing.Internet communication equipment, generally by interchanger, router, optical transmitter and receiver group
Into these equipment complete the functions such as packing, unpacking, routing, the signal conversion of data, and in communication process, data are generally adopted
With the conventional cryptographies mode such as AES, DES, RSA, encryption intensity depends on key length, if improving the security of communication data,
Special equipment must be used, increases considerably the length (reference paper 1 of key：《Cipher scheme study》, Zhang Xiaofeng, Fan Qi
China, Cheng Hongbin etc.,《Computer technology and development》, 2006.2).Current industrial internet communication is general only using communication apparatus
Focus on industrial environment safety, for data communication mostly only with conventional cryptography mode, key length is shorter, it is impossible to reach high series
According to the requirement of safety.
For protect factory and industrial equipment from unauthorized access, sabotage, spy and malicious attack are, it is necessary to industry
Equipment product safe to use or security solution.Network communication is key link safe involved in informatization process,
The encryption communication method of research and development safety is needed, enhances the security of communication process, has to the data message transmitted in network
Effect protection.Legacy network devices are inadequate to the protecting data encryption of communication, suitable for application in the higher work of information security demand
In industry information network.And administrative staff's human configuration key is generally required in current industrial information network, there are human factors
Hidden danger of divulging a secret.
The content of the invention
The present invention needs human configuration management, legacy network devices pair for key present in current industrial information network
The problem of encryption of communicated data protection is inadequate provides a kind of based on the encrypted industry internet communication encryption side of dynamic random
Method.
It is provided by the invention to be based on the encrypted industry internet communication encryption method of dynamic random, using dynamic random mode
Key is generated, is specifically included：
In communication both ends clocked flip dynamic key production process；
Both ends communicate in locally generated random number, and carries out random number exchange, is owned by communication both ends locally generated
The random number that random number and other side generate；
Both ends communicate according to two random numbers, by key schedule, generates identical key；
Both ends communicate in communication process, AES (Advanced are carried out using identical key to data message
Encryption Standard) encryption and decryption.
The advantages and positive effects of the present invention are：
(1) the method for the present invention by randomly generating, dynamic interaction, the cipher key calculation method locally generated so that key without
Human configuration management is needed, effectively prevents the key leakage hidden danger that human factor is brought；
(2) the method for the present invention makes communication both ends (client and server end) in the case where that need not exchange key, realizes
Coded communication, so as to effectively reduce the security risk brought in network transmission cipher key processes.
Description of the drawings
Fig. 1 is the signal of the realization process based on the encrypted industry internet communication encryption method of dynamic random of the present invention
Figure.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and examples.
It is provided by the invention a kind of based on the encrypted industry internet communication encryption method of dynamic random, as shown in Figure 1, bag
4 key links are included, are clocked flip respectively, random number is generated with exchanging, key generates, data encrypting and deciphering.It is explained in detail below each
A link.
Step 1, clocked flip.Using a software timer, according to the cycle of setting, timing performs key and generated
Journey, dynamic change the key at communication both ends.
Step 2, random number is generated with exchanging.Client using Generating Random Number, generates random number first, and will production
Server end occurs for raw random number, the random number that server end to be received is waited to return；Received server-side to client with
After machine number, using Generating Random Number, random number is generated, and the random number of generation is occurred to client.
The cycle and the time of exchange random number that random number generates can manually preset.
Step 3, key generates.Communication both ends are respectively using the random of locally generated random number and the other side that receives
Number produces algorithm according to identical key, calculates and generate identical key.
Since key uses two generating random numbers of communication two party timing generation, the security of key can be effectively improved.
In the embodiment of the present invention, two random numbers and key are generated as follows：
(1) random number generates：Random number is generated using the random function in standard C storehouses.
(2) key generates：It is raw by exclusive or, same or with linear feedback shift operator combination using 2 random numbers
Into key.
Step 4, data encrypting and deciphering.Communication both ends using identical key to respectively to the data message that sends and receives into
Row AES encryption and decryption.
Dynamic key is periodically generated in communication process by above-mentioned steps, key is without human configuration management, by network
Terminal device carries out automatically, the key leakage hidden danger that human factor is avoided to bring, and reduces in network transmission cipher key processes
The security risk brought.
